Abstract (en)
A cardiotomy section (2) includes a filter (10) and a defoamer (20) arranged inside the filter. A lower end (11a) of the filter is sealed or folded in an approximately straight line or in a curve, and the defoamer is annularly arranged along the inner peripheral surface of the filter, as viewed from above. A conduit tube (90) that introduces intracardiac blood is inserted from above downward in the cardiotomy section. A lower end of the conduit tube is located at the same level as or at a lower level than the lower end of the defoamer, with respect to the vertical direction. In a projection view of a lower end face of the defoamer with respect to a horizontal plane, (Ru2-2×Tu)/(Ru1-2×Tu)‰¤0.24 is satisfied, where Ru1 is the outer dimension of the annularly arranged defoamer in a major axial direction, Ru2 is the outer dimension thereof in a minor axial direction, and Tu is the thickness of the defoamer. This achieves a blood reservoir equipped with a cardiotomy section having high defoaming performance.
